A commercial jetliner with an air speed of 640 mi/hr leaves Chicago and flies due west at the same time that a small single-engi

Vilka [71]

Answer:

40 mph

Step-by-step explanation:

The speed of separation of the two airplanes traveling in opposite directions is the sum of their respective airspeeds:

640 mi/h + 180 mi/h = 820 mi/h

At the time of interest, their separation distance is ...

1500 mi + 550 mi = 2050 mi

Then the time it took to achieve that separation was ...

time = distance/speed = (2050 mi)/(820 mi/h) = 2.5 h

__

The actual ground speed of the jetliner was ...

speed = distance/time = 1500 mi/(2.5 h) = 600 mi/h

Since the airspeed of the jet is 640 mi/h, the speed of the air must have subtracted 40 mi/h from its headway.

The wind from the west is 40 mi/h.

_____

Check

The wind adds to the speed of the small plane, so its ground speed is ...

180 mph +40 mph = 220 mph

and the distance it travels in 2.5 hours is ...

distance = speed × time = (220 mi/h)(2.5 h) = 550 mi

This value matches the problem statement, so the answer checks OK.

HELP ME PLS!!!!!!!!!!!!!!!!!!!

Advocard [28]

the number inside the parenthesis includes the interest rate ( annual percentage

looking at the possible functions, if you raise the interest rate to the power of 12, you would need to divide the number of years (t) by 12 as well

so the function could be rewritten as A=1000(1.023^12)^t/12

since the annual percentage rate is 2.3% ( 0.023)

divide 0.023/12*100 = 0.19% per month interest

A rescue helicopter flew from its home base for 35 kilometers on a course of 330 degrees to pick up an accident victim. It then

artcher [175]

I've drawn a triangle to represent the journey (see attached.

The angle from Home to Victim to Hospital is:

a = $90 - (360 - 330) = 90- 30 = 60^o$

Using the cos rule, we can solve for the length x:

$a^2 = b^2 +c^2 - 2bccosA
\\x^2 = 35^2+25^2-2(35)(25)cos60
\\x^2 = 1850 - 875
\\x^2 = 975
\\x = \sqrt{975}
\\x = 31.2249...$

Using the cos rule, we can solve for angle b:

$a^2 = b^2 +c^2 - 2bccosA
\\35^2 = 31.22...^2+25^2-2(31.22...)(25)cosb
\\1225 = 975 + 625 - 1561.249...cosb
\\-375 = -1561.249...cosb
\\b = cos^{-1}( \frac{-375}{-1561.249...}) 
\\b = 76.1...$

So the bearing the helicopter has to travel is:

270 - 76.1 = 193.9 degrees (1 dp)

And the distance it travels is 31.2 km (1 dp)
